El Reg has an in-depth review of the XO laptop. They conclude: "There's a lot to like about the XO laptop. It's tough, it's great as an eBook reader, it has a big (for its category), high resolution screen. It runs silent and cool, has good battery life, and the clean design of the Sugar interface is easy to use. But several areas need work. The browser should be replaced by Firefox, and the Journal needs to support folders to match how people actually organise their work and play. Multimedia performance needs to be improved, which can hopefully be done through software. The XO needs a unified media player that supports all media types, along with playlists, and should be integrated with the UI. Most of these changes come down to the OLPC organisation placing more emphasis on real-world usability and less on their ideals of a perfect interface. If they can manage to do this, the XO laptop could be a great tool for learning and play."

I stopped reading at the "The browser should be replaced by Firefox" statement. Yeah. I can see in my imagination children waiting couple of minutes for it to open. Not mentioning the energy waste.

I didn't stop reading, but when he said that Opera was already available, IMHO probably the best portable browser out there(and certainly one of the best for low-power systems), I did think that his browser complaints were baseless and his review skewed.
